Abstract: A washing installation for washing machined parts having internal ducts comprises a pair of axially spaced article-holders (2) mounted on a common drive shaft (9), and a transfer device (1) for transferring articles (7) to be washed to the holders (2). Each holder (2) is rotatable step-wise from an article-loading and unloading station and through a plurality of washing stations before returning to the loading and unloading station, and a plurality of holding locations (3) are provided on the holder (2) to hold a plurality of articles (7), there being provided a washing box (5) at each holding location for applying washing medium to the article (7). The latching devices (8) are provided one at each of the holding locations (3) for holding the articles (7) in position at all times other than when the holding location is at the loading and unloading station. 
     In order to improve the washing action to be applied to each article (7) and particularly to the internal ducts thereof, each washing box (5) is connected to a corresponding one of the latching devices (8) for movement therewith so that, when the latching device (8) moves to the latched position, the article (7) is held firmly in position in the holding location (3) and also against the washing box (5). 
     In order to prevent handling problems during the loading and unloading of the articles (7). it is preferred that the supply of washing liquid to the washing boxes should be controlled so that no washing liquid is supplied to a washing box (5) when the latter has been moved with the holder (2) to the loading and unloading station.

Abstract: A manifold for an internal combustion engine comprises a plurality of body parts (1,12,17) each formed as an integral casting preferably by pressure casting. A first body part (1) has a mounting flange (2) for the manifold, a plurality of open channels (6) communicating with respective apertures (4) in the mounting flange, and a water chamber (8) communicating with a port (9) in the flange and a further port (10) in the first body part. A second body part (12) overlies the channels so that the first and second body parts define a plurality of gas conduits effecting communication between the apertures and a common orifice (7). The first and second parts are sealed together along opposed side faces (22,25) adjacent their outer peripheral edges, rather than along abuting end faces. This allows access to the joints from the exterior of the assembly, permitting connection by electron beam welding or an adhesive, since all the joints are located on the exterior of the assembly a smooth interior surface is preserved and visual inspection of each joint is possible as it is made.

Abstract: Eine Drosselspule besteht meist aus Kernsäulen, die durch Joche (4) miteinander verbunden sind, wobei die Kernsäulen aus einzelnen, durch unmagnetische Zwischenlagen (3) voneinander getrennten, radialgeblechten Paketen (2) bestehen. Sowohl die Kernsäulen als auch die Joche (4) besitzen zylindrische Ausnehmungen, die zur Aufnahme von zentralen Zugbolzen dienen, mit deren Hilfe die gesamte Konstruktion gepreßt und gehalten wird. Der Magnetfluß wird durch diese Ausnehmungen gezwungen, quer zu den Blechen in die Randzonen auszuweichen, wodurch es an den Ausnehmungsrändern zu erhöhten Wirbelstromverlusten und zu gefährlichen Erwärmungen kommt. Um derartige Nachteile zu vermeiden, weisen die den Jochen (4) anliegenden Pakete (2) der Kernsäulen in Richtung der Joche (4) sich im Querschnitt keilförmig erweiternde (7) und die Joche (4) im Querschnitt rechteckige (6) unmagnetische Zwischenlagen auf.

Abstract: A reversible ratchet tool has a toothed drive ring and a coaxial toothed core (40). A pivotal toothed double-ended pawl (90) is secured to the core and is selectively shiftable to intercouple the driving ring teeth (34) with the core for driving the core and hence any tool element in either of two opposite senses of rotation. The means for pivotally shifting the pawl are responsive to finger pressure applied to switch- like arms (176,178) to effect, through intercoupling linkage of a shaft (130) and spring loaded probe (146) bearing on an undersurface of the pawl the pivotal shifting between first and second driving-ring-engaging operational positions. The pawl shifting means is manipulable with the same hand used to hold and to operate the tool, and there is provided a dif- 'ferentiated surface (180) of one arm (176) of the switch whereby the tool user may palpably or visually perceive in  I  which rotational mode the tool is set.

Title: Smoke detector with a pulse-actuated radiation source
Inventor: MUGGLI JURG DR DIPL PHYS
IPC: G01N21/53
Filed: 1982-05-13
Abstract: A smoke detector contains a pulse-operated radiation source and a radiation receiver arranged externally of the region directly irradiated by the radiation source. The radiation receiver, in the presence of smoke in the radiation region, is impinged by scattered radiation and delivers output pulses. There is provided an evaluation circuit which generates a blocking pulse, and which inputs a resetting signal to a counter device in consequence of the difference of the blocking pulse and output pulse of the radiation receiver. The counter or counting device, in the absence of a resetting signal, is switched further and upon reaching a predetermined counter state triggers an alarm signal. High-frequency electrical disturbances which arise, as long as the radiation source delivers radiation pulses, at most can generate an additional resetting signal for the counter, so that the integrity of the smoke detector against triggering of false alarms is enhanced. If there is connected in parallel to the radiation receiver a NTC-resistor, then there is obtained a smoke detector which responds to a further combustion criterion (temperature).
